Review Clock

Track how long you spend reviewing GitHub pull requests. See cumulative weekly stats and effort estimates.

Review Clock adds a lightweight timer to every GitHub pull request page so you can see exactly how long you spend reviewing code. Live Review Timer A compact floating timer appears automatically when you open a GitHub PR. It tracks active review time, pausing when you switch tabs, minimize the browser, or go idle. Click to expand and see the PR title, or pause/resume manually. Effort Estimation Before you dive in, Review Clock shows the PR size at a glance — Small, Medium, Large, or XL — based on the number of files changed and lines added/deleted. Get a rough time estimate so you can plan your day. Weekly Stats Dashboard Open the popup to see your review activity for the week: - Total review time across all PRs - Number of PRs reviewed - Average time per review - Your longest review session - A daily breakdown bar chart (Monday through Sunday) Recent Reviews See your last 10 reviewed PRs with links back to the PR, repo name, duration, and date. Toggle to view previous weeks. Smart Pause & Resume The timer automatically pauses when: - You switch to another tab - The browser window loses focus - You go idle for 2+ minutes (configurable) It resumes when you come back and start interacting with the page.
